Bad printing Why is this build failure happening?

Hello everybody i don’t now way is happening is new printing and i tried with the black material and grey white property same

Looks to me like you are using a rather low viscosity resin. The pigment may be separating and causing those failures.

Also I don’t see any supports on the inside of the ring. You may need a few in there for the overhangs that are created by the details of the ring.
